Summary The deepening of the sensors of the surface locating system under the low-velocity zone compensates for the influence of inaccuracy in the knowledge of the velocity model in the upper part of the section, reduces the level of registered surface noise and expands the upper limit of the operating frequency range. All this increases the sensitivity to weak events and the accuracy of event location in general. The formation of a hydraulic fracture leads to a change in filtration flows in the reservoir in the well area, which in general should affect the change in flow rate not only in the well with hydraulic fracturing, but also in the adjacent wells. Correlation analysis between daily fluid flow rates in wells before and after hydraulic fracturing, in the presence of statistical relationships, allows to establish a change in the direction of fluid movement in the considered element of the development system and to give a qualitative assessment of the fracture azimuth obtained from the results of microseismic monitoring.

Summary The presented work describes a new technology for detecting gas and water breakthrough in long horizontal wells during field development in the Caspian Sea. This technology made it possible to determine the intervals of gas breakthrough using a mini-chromatograph directly in the field and did not require processing in a specialized chemical laboratory.

Summary Year by year drilling of horizontal wells becomes more and more popular way of the field exploration. For instance, at the beginning of XXI century the quantity of drilled horizontal wells from the whole amount was just about few percentages, if to say that nowadays this number is getting closer to 60%. Despite on that fact, that designing and exploration of oil & gas fields are such laborious processes, the main problem is still lies on the low level of EOR. Nowadays geosteering becomes an essential part of well drilling and increases the level of well targeting, therefore it enhances the level of extracted hydrocarbon fluid. Analyzing drilling datas, received in a real time from the wellbore, geosteering provides an opportunity to correct the planned trajectory of the well instantly and therefore make sure that the well stays in a target zone.

Summary NDP «Chepakovskoe» uses advanced logging while drilling technologies for studying the fracturing of Paleogene reservoirs of Chepakovskoye oil field (Stavrovol region). High-resolution microimager while drilling in horizontal well provide new information of complex structure of the Paleogene deposits which cannot be unambiguously characterized by standard logging methods. For example, wide development of natural fracturing according to core data cannot be taken into account according to the standard logging complex. At the same time, the data of high-resolution images made it possible to significantly detail the structural elements of the reservoir, to characterize the natural and drilling-induced fracturing of the rock. Main attention in this article is given to the analysis of fracturing of reservoir horizons, estimating of fracture density (frequency) along the wellbore and the determination of fracture aperture.
